Pentagon's $4.6 Billion Background Check System Still Broken, Congress Told

Why it matters

The Department of Defense's troubled background check system — now in its second decade of modernization — still lacks a reliable delivery schedule, the Government Accountability Office told lawmakers on February 24, 2026. The hearing before the House Oversight and Government Reform Committee's Government Operations Subcommittee exposed a sharp divide between the Trump administration's promises of cultural reform at the agency responsible for vetting over four million security-cleared personnel and the GAO's blunt assessment that execution remains the fundamental problem. The Defense Counterintelligence and Security Agency has operated without a permanent director since September 2025 — a vacancy that drew pointed criticism from lawmakers in both parties.

The big picture

This hearing is the third in a series stretching back to June 2024, when the subcommittee first examined the National Background Investigation Services system, known as NBIS. A follow-up hearing was scheduled for September 2025 but was postponed.

The backstory: President Trump created DCSA during his first term in 2019, transferring the background investigation mission from the Office of Personnel Management after a catastrophic 2015 data breach compromised over 21 million records. NBIS was supposed to be operational by 2019. It is now projected to cost $4.6 billion and require another $2.2 billion through 2031.

A new GAO report (GAO-26-108838), timed to the hearing, found that DCSA paused the NBIS program in early 2024 after missing multiple milestones. Despite a programmatic "reset," the schedule remains unreliable. Federal agencies have not met timeliness goals for nearly all phases of the security clearance process, according to the report.

The administration's stated goal is accelerating Defense Department background checks and security clearances. But the five-month leadership vacuum at DCSA and the GAO's findings suggest a gap between rhetoric and results.

What they're saying

The hearing featured two witnesses offering starkly different framings of the same problem.

Alissa Czyz, Director of Defense Capabilities and Management at GAO, focused on execution risk. She warned that DCSA's project schedule for NBIS "is still not reliable," even as the Pentagon eyes a 2028 delivery date. She noted that while DCSA now has a reliable cost estimate, "delays have caused the price tag to balloon."

Justin Overbaugh, Deputy Under Secretary of Defense for Intelligence and Security and Acting DCSA Director, centered his testimony on culture. He delivered a candid indictment of the agency he inherited:

ClearanceJobs captured the tension between the two witnesses: while GAO focused on execution, Overbaugh described "an attempt to overhaul the culture of DCSA itself, shifting from compliance-driven caution to mission-driven innovation."

Rep. Pete Sessions (R-TX-17), the subcommittee chair, kept pressure on both the bureaucracy and the White House. In his opening statement, he said the hearing's focus was on "whether the program is on track to support the administration's stated goal of accelerating background investigations and security clearances." He pointedly added that he looked forward to "hearing more about progress towards hiring a new DCSA Director."

Rep. Tim Burchett (R-TN-2) pressed Overbaugh on cultural dysfunction within the agency, asking what concrete steps DCSA had taken to address internal impediments to progress.

Political stakes

Overbaugh made public commitments he will be held to. He testified that by the end of 2027, DCSA would deploy core NBIS shared services, and by the end of 2028, the agency would operationalize the full Trusted Workforce 2.0 model. Those dates now function as accountability benchmarks. If DCSA misses them — as it has missed every prior deadline — Overbaugh will face a far less patient Congress.

For the Trump administration, the NBIS debacle is an awkward fit with its government efficiency narrative. A $4.6 billion IT program that has missed repeated deadlines, combined with a five-month vacancy in the DCSA director's chair, undercuts the message that this White House is cutting waste and filling critical national security posts.

The hearing also carries real constituent stakes. Members like Rep. Gerry Connolly (D-VA-11) and Del. Eleanor Holmes Norton (D-DC-1) represent districts dense with defense contractors and federal employees directly affected by clearance delays. The Professional Services Council estimates contractors spend around $400,000 annually on costs tied to those delays.

Yes, but

This is not a clean partisan fight. The DCSA background investigations mess spans four administrations. The 2015 OPM breach that triggered the transfer happened under Obama. The Biden administration oversaw the 2024 program pause. And the Trump administration created DCSA in the first place. That shared culpability limits the attack surface for either party — and explains why the hearing's tone was more exasperated than adversarial.

Overbaugh also pointed to real progress. DCSA reportedly reduced its security clearance backlog by 24 percent, and the GAO acknowledged the cost estimate is now reliable even if the schedule is not. The question is whether incremental improvement is enough for a program that was supposed to be finished seven years ago.

What's next

The committee's post-hearing wrap-up referenced a push to close GAO's recommendations within one year — setting a February 2027 checkpoint that will likely trigger another congressional hearing on DoD personnel vetting if the recommendations remain open.

The FY2027 National Defense Authorization Act, now working through Congress, is the most likely legislative vehicle for action. The GAO has recommended that Congress require DCSA to develop a reliable schedule and cost estimate — language that could be incorporated as an NDAA provision. Lawmakers in the House Armed Services Committee are also advancing provisions in the FY2026 NDAA to allow contractors to staff classified programs while employees wait for clearances.

The bottom line

The Pentagon promised a modern background check system by 2019, has spent $4.6 billion, and still cannot tell Congress when it will be done — and the agency running the effort does not have a permanent leader.
